CARPET-CLEANER.

Specication of Letters Patent.

Application; lldd December 4, 1912. Ssrallo. 7343935 To lll whom it may concern Be it known that I, HENRY B. Nnw'rsoN, aI citizen of the United' States, residing at Bloomington, in the county of McLean and which the finer particles of dirt or dust may i combined dust receptacle and nozzle.

be cleanedfrom a carpet or rug'.

The object of the invention is primarily to improve the suction device, especially the construction of the suction nozzle and dust receptacle, in order to furnish a simple, compact, and elicient mea-ns by which the dust and fine dirt may be drawnfrom the carpet into dust compartments in the suction devlce.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles of the invention.

Figure 1 is a side elevation of a carpet cleaner involving the features of my invention. Fig. 2 is a central vertical sectional View. Fig. 3 is a perspective View of 1g. 4 is a perspective view of the screen. Fig. 5 is a perspective view of a base board' of one of the bellows. Fig. 6 is a transverse section of the device.

In the preferred embodiment of my invention I employ the suction cleaner in connection with the usual carpet sweeper, andl in this connection the rotary brush or sweeper 1 is carried by the shaft 2 which is rotated from the shafts 3 and 4 upon which the traction wheels 5 and 6 are mounted. The shafts 3 and 4 are supported in the sides 7 of the dust box or receptacle 8, and the receptacle is provided with the usual movable trays 9 that may be turned to empty the accumulated dust in well known manner.

It should be understood that the shaft 2 and the brush 1 are rotated from the wheels 5 and 6 through the medium of the intermediate wheel 1-0 in the usual manner.

The shaft 3 is preferably supported in slots 11 in the sides 7 of `the dust receptacle,

and ai spring 152 provides a exble bearing for this shaft. This spring allows the wheels 5 to rise if an obstruction is encountiered, but insures that the apparatus shall remain close to the carpet, for a purpose to be described.

The dust receptacle 8 is provided with a removable cover 13, which, by means of screws 14, is removably held on top of the dust receptacle.

I employ a plurality of bellows or pumps, one of which is illustrated in section in Fig.

l`2. rFliese bellows or pumps are located within the cover 13 and over the dust receptacle '8, thel base board 15 being rigidly secured above the dust receptacle 8, and proiront of the device. These bellows or pumps are operated from the shaft 4 which is provided with several cranks 16 te which the links 197 are connected. In Fig. 2 the actuating part of the bellows is illustrated (ipartly 1n dotted lines). A link 17 for each pump is pivoted at 18 to the lever 19 which is iulcrumed at 20 on ,the base board 15. The opposite end of the lever is pivoted to the link 21. secured to the upper board 22 of the bellows.

Assuming that there are three bellows or pumps, the cranks 16 are arranged at intervals of. 120 degrees so that the bellows will be operated alternately from the movement of the carpet sweeper over the carpet. Each movable board 22 of the bellows is provided with outwardly openin Hap valve 23, and the base board of each bellows is provided with an opening 24.

The three openings 24 of the base boards are adapted to aline over the openings 25, 25, 25', of the screen frame 26. This frame is clamped against the under side of the base boards of the bellows, the openings 25 alining with the openings 24 of the boards, but the openings 25 are closed at t-he underside of the frame by a foraminous screen 27 of fabric or other suitable material that will not pass dust. The upper side of the frame is provided with a gasket 28, of chamois skin or other material to form a packed joint.

The dust receptacle 29 is formed with par titions 30 which divide the receptacle into three compartments 31, 31, 31, and each of these compartments is in communication,

`ecting beyond* the dust receptacle at the' through a screened opening 25 with the'n slotted base board of a bellows, thus formng in reality a part of the pumps or belows. At the forward lower edge of the receptacle 29 a nozzle 32 is formed, a wearing plate 33, of metal, being placed on the under" side of the nozzle for contact with the carpet;

or rug to be cleaned. A slot 34 extends the entire length of the nozzle, and yabove the nozzle the slot merges into a continuous passage 35 extending across the entirev front of the box and at the top of this passage are formed valve seats 36, one of which is located in each compartment 31. Upon each valve seat is an upwardly `opening intake valve formed of a flexible strip 37 reinforced by a metallic strip 38, one edge 39 of the strip 37 being secured to the valve seat.

It should be understood that the check or intake valves, each permit passage of dust to its own compartment 31, when the bel lows is' properly actuated.

The dust receptacle and nozzle are readily attached to and detached from the cleaner, by means of the cam levers 40, one of which is pivoted in ears 41 at each end of the box.

' `The levers each have a bent arm 42 provided with end hooks 43 adapted to hook over the pins 44 on the cover 13.' In Fig. 3 the clamp is illustrated in released position. In Fig. 1

' the hooks are shown engaging the pins, and

the cam lever is turned down, thus clamping the dust receptacle tightly against the under side of the bellows base boards.

In Fig. 3 it will he observed that a cleat 45 is attached atQthe inside lof each end of the receptacle and that the partitions 30 do not extend up flush with the top of the sides of the receptacle.4 rIhe screen 26 is of a size to neatly fit within the receptacle and rest upon the cleats and partitions, but the flexible gasket 28 which extends beyond the frame 26 at all sides, is adapted to be clamped between the upper edges of the receptacle and the under sides of the base boards, (as in Fig. 2) and in this manner the gasket provides an air tight joint between the removable box and sweeper.

In operationit is evident that the rotation of the crank shaft 4 will actuate the bellows or pumps. -The movement of the bellows causes a suction through the nozzle which l lifts the check valves 37 and' draws the dust into the compartments 31, the oraminous screen 27 preventing `passage of the dust noeavao through the bellows, but permitting` passage of air through.y the screen, bellows and out through exhaust valves 23. In this manner the check valves 37 are alternately opened or closed to suck or draw compartments. l

The dust compartments are Dart of the pumps or bellows,and by this construction I am enabled to collect the dust in the pumps by drawing itA through'the check valves and, by the screen, preventing its passage through the exhaust valves.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is c f l. rIhe combination in a carpet cleaner 0f -a dust receptacle having a nozzle, and parthe dust into the dust 'titions forming-compartments, a valve between the nozzle and each compartment, a

-foraminous' screen over vthe* compartments,

and a valved bellows complementary to each compartment and located over the screen.

2. 'Ihe combination in a carpet cleaner of a dust receptacle` having a nozzle, and fpartitions forming compartments, a valve be-k tween thenozzle and each compartment, a oraminous screen over the receptacle,` a slotted base boa'rd projecting over thescreen,

and a plurality of bellows, complementary to the compartments,` of which the base board forms a part.

3. The combination 1n a carpet cleaner with a suction' device, of a dust receptacle having an open top and a cleatateach end, partitions in. the receptacle4 forming compartments, a nozzle common toall compartments, a valve between the nozzle and eachy compartment, and a removable frame resting on said cleats andhaving a foraminous screen closing the receptacle.

4. The combinationwith a carpet' cleaner of a plurality of bellows having a common, slotted base board, of a detachable dust receptacle and means for securing it under the slotted base "board, partitions forming compartments in the receptacle and a valve for each compartment, a screen, and a nozzle n for the receptacle.

In testimony whereof I aflix my signature in presence of twoV witnesses.
